Tree and Limb Impact Damage
Emergency A falling limb or whole tree can crack shingles, punch through decking, break rafters, and leave the inside of the house open to rain. Even a medium-sized branch dropped from 60 feet can break decking boards and tear underlayment loose.
Why it happens here Atlanta has one of the densest urban tree canopies in the country. Mature water oaks, red oaks, tulip poplars, and loblolly pines hang over most homes. Water oaks especially get weak and hollow as they age. Spring thunderstorms, fall wind events, ice storms, and tropical remnants like Helene all bring limbs down. Helene's multi-day rain soaked the red clay, so full trees tipped over at the root. That's why limb strikes cause more storm damage here than hail does.
Signs to watch for - Visible branch or tree resting on the roof
- Daylight or water coming through the attic or ceiling
- Sagging rooflines or cracked rafters
- Broken or missing shingles in a concentrated area
- Dented gutters or torn-off fascia
- New ceiling stains right after a storm
Local patterns We see this most in heavily wooded lots in Druid Hills, Pine Lake, Smoke Rise, Medlock Park, and Riverside/Huntcliff in Sandy Springs. Mature hardwoods there often stand within a few feet of the house. Calls spike after spring squall lines and any tropical system that reaches the metro.
Our fix Once the tree service clears the debris, we tarp and dry in the opening. Then we document the damage for insurance, replace broken decking and framing, and blend new shingles into the existing roof.

Hail and Wind Storm Damage
Serious Hail bruises shingles, knocks off granules, and cracks the asphalt mat underneath. Straight-line winds break the seal strips, lift shingle tabs, and blow off ridge caps. The damage often can't be seen from the ground but still shortens the roof's life.
Why it happens here Georgia regularly ranks among the higher-volume states for hail insurance claims. Atlanta's severe-storm season peaks from March through May and comes back in fall. Shingles that have already been baked for years break down faster after a hit, because the heat has made the asphalt brittle. Wind damage is common on the big, exposed roofs of two-story homes. After every major event, out-of-state storm chasers move in, so getting an honest local inspection really matters.
Signs to watch for - Dark circular bruises or exposed mat on shingles
- Heavy granule buildup in gutters and at downspouts
- Dented gutters, vents, or AC fins
- Creased or lifted shingle tabs
- Missing ridge caps or shingles in the yard
- Door-knockers appearing in your neighborhood after a storm
Local patterns Large 1970s–90s roofs in Dunwoody's Georgetown, Lilburn, and Tucker's Embry Hills take a lot of wind and hail. North Fulton and DeKalb get hit hard by spring storm lines. Older 3-tab roofs in these neighborhoods often fail after one bad hailstorm.
Our fix We do a detailed inspection with photos and give you an honest call on whether the damage justifies a claim. We can meet your adjuster. Then we repair or replace the roof to code.

Heat-Damaged Shingles from Poor Attic Ventilation
Serious When an attic can't vent heat and moisture, the shingles cook from underneath. They blister, curl, and lose granules years early. Condensation can also grow mold on the decking, and cooling bills climb.
Why it happens here July highs near 90°F and dewpoints in the 70s turn under-vented Atlanta attics into ovens. Air temperatures there can pass 140°F. Many post-war ranches were built with a few small gable vents and no soffit intake. Later re-roofs often added ridge vents without fixing the intake, and that doesn't work. Pre-war homes with knob-era attics have the same trouble. The result is shingle aging that's out of proportion to the roof's age.
Signs to watch for - Blistered or curling shingles on south and west slopes
- Attic that feels unbearably hot in summer
- Musty odor, dark staining, or mold on attic sheathing
- Rusty nail tips poking through decking
- Rising upstairs cooling costs
- Rippled or wavy roof surface
Local patterns This shows up all over the ranch neighborhoods of Tucker, Chamblee, Doraville, Belvedere Park, Scottdale, and Northlake (30345). It's also common in Craftsman bungalows in Kirkwood and Candler Park, where attics were never designed to breathe.
Our fix We size intake and exhaust to match the attic. That means adding soffit vents, ridge venting, or attic fans and replacing moisture-damaged decking during the repair or re-roof.

Clogged Valleys, Gutter Overflow, and Fascia Rot
Moderate Leaves and pine needles build up in roof valleys and gutters, and water backs up under the shingles. Over time the fascia boards, soffits, and roof edges rot, and leaks appear at valley intersections and along the eaves.
Why it happens here Oaks drop leaves in fall, pines shed needles year-round, and spring brings a pollen-and-catkin mess. With about 50 inches of rain a year and no dry season, clogged gutters overflow almost all the time. Overflow splashes onto red Georgia clay, which stains siding and walkways and can add to foundation settling in older homes. Shaded valleys stay wet for days, so the underlayment and wood under them break down quickly.
Signs to watch for - Water spilling over gutters during moderate rain
- Plants or seedlings growing in gutters
- Soft, peeling, or darkened fascia boards
- Leaks near valleys or interior corners
- Red clay splash staining on siding or walks
- Gutters pulling away from the house
Local patterns This is constant under heavy canopy in Pine Lake, Druid Hills, Medlock Park, Lakeside, and Avondale Estates. Pre-war homes with built-in box gutters are a particular problem, because a hidden leak can quietly rot the rafter tails.
Our fix We clear the valleys and gutters, replace rotted fascia and decking, and upgrade valley flashing. Where the canopy calls for it, we add gutter guards and recommend limb clearance.

Failed Flashing, Pipe Boots, and Chimney Leaks
Moderate Flashing seals the joints where the roof meets chimneys, walls, skylights, and vent pipes. When the metal corrodes, the sealant cracks, or rubber pipe boots split, water gets into the wall cavity and attic even though the shingles look fine.
Why it happens here Atlanta's daily heat swings and strong UV crack rubber pipe boots in as little as 8–12 years. Older intown homes often still have their original chimney flashing, sometimes covered over with roofing cement during earlier re-roofs. Skylights on 1980s roofs in Dunwoody and Sandy Springs are reaching the age where seals fail. With rain all year, even a small gap leaks often.
Signs to watch for - Ceiling stains near chimneys or bathroom vents
- Cracked rubber collars around plumbing pipes
- Tar or caulk smeared heavily around chimneys
- Damp drywall on walls below roof-to-wall joints
- Fogged or dripping skylights
- Rust streaks on metal flashing
Local patterns Chimney leaks are common on Tudor and Colonial Revival homes in Druid Hills, Historic Brookhaven, and Winnona Park. Skylight and step-flashing leaks show up across 1980s subdivisions in Georgetown and Riverside/Huntcliff.
Our fix We remove the old flashing and install new step, counter, and chimney flashing or a new skylight flashing kit, along with new pipe boots. Your shingles stay in place wherever possible.

Low-Slope and Flat Roof Failures
Serious Roofs with very little pitch don't shed water fast. Standing water, failing seams, and blistered membranes cause leaks, especially when someone put shingles on a slope that was too shallow for them.
Why it happens here Mid-century modern homes in Northcrest and near Lavista were designed with flat or very low-slope roofs. Many post-war ranches added carports, porches, and back rooms with low-slope roofs. Atlanta's heavy thunderstorm downpours put a lot of water on these surfaces quickly. If drainage is weak or shingles were used below their minimum slope, leaks follow. Summer heat also ages exposed membranes.
Signs to watch for - Ponding water 48 hours after rain
- Bubbles, cracks, or alligatored surface
- Open or lifted seams
- Shingles on a nearly flat addition
- Leaks at the joint between addition and main roof
- Clogged scuppers or drains
Local patterns This is concentrated in Northcrest (Doraville), mid-century pockets of Chamblee and North Druid Hills, carport conversions throughout Tucker and Scottdale, and small commercial buildings along Buford Highway.
Our fix We tear off the failed material, fix the drainage, and install a proper membrane system: modified bitumen, TPO, or EPDM, flashed correctly to the main roof.

Algae Streaks, Moss, and Lichen
Minor The black streaks on many Atlanta roofs come from an algae called Gloeocapsa magma, which feeds on the limestone filler in shingles. Moss and lichen hold moisture against the shingles and gradually lift and loosen them.
Why it happens here Shade plus humidity is all this growth needs, and Atlanta has plenty of both. North-facing and tree-shaded slopes may never fully dry between rains. Algae is mostly cosmetic at first. Moss is a bigger problem, because it holds water against the roof and pushes up shingle edges, which shortens the roof's life.
Signs to watch for - Black or dark-green streaks down slopes
- Green moss clumps on shaded areas
- Gray-green crusty lichen patches
- Lifted shingle edges around growth
- North-facing slopes aging faster than others
Local patterns Most common on the shaded north slopes of homes in Druid Hills, Pine Lake, Smoke Rise, Candler Park, and Lakeside. Homes on wooded lots there may get only a few hours of direct sun a day.
Our fix We clean the roof gently with a low-pressure, shingle-safe treatment and fix any shingles the growth has lifted. When it's time to replace, we recommend algae-resistant shingles.
